Hi,
I experience very strange problem: GC somehow collects live
objects.
I found it because i got segfaults. After debugging and tracing i
found this is because of accessing not allocated memory.
I did the following checks:
- added to some class invariant check for access to suspicious
members with assertion
assert(GC.addrOf(cast(void*)x) !is null);
where it fails DETERMINISTICALLY at some point
- printing address of allocated classes where i observe the
following pattern
-> ctor
check
check
check
<- dtor
check (fails)
could anybody advice me with something? I got really frustrated
by this strange behaviour which i can not fix right now.
key observations:
- it is deterministically behaviour (what gets me even more
confused cause GC collections as far as i know runs from time to
time)
- i do not play with pointers optimisation like hiding its in
ints or floats.
- i operate with large uniformly distributed (video) data in
memory where pointer like patterns may occur. but this is not the
case cause (1) it brings at worst long living objects (2) input
sequence constant but allocated pointers each run different.
